nd opposite Siberut.The total area reached 6011.35 km2 with a population numbered 384 718 inhabitants, covering 17 Districts. The Mentawai archipelago has been ecologically isolated from mainland Sumatra since the mid-Pleistocene period, resulting in high levels of endemism amongst its indigenous flora and fauna. Siberut is largely covered with primary dipterocarp and mixed forest, as well as smaller areas of secondary forest and freshwater, sago, and mangrove swamps. High conservation value has attracted the attention of World Wide Fund for Nature and United Nations body UNESCO resulting in the declaration of the Siberut National Park (Taman Nasional Siberut) encompassing slightly less than half of the island. Siberut has attracted most attention from culture/nature tourists and researchers. The island has an area of approximately 500 800 hectares and has a population of around 22,500 citizens, 90% of whom are indigenous Mentawaians. http://www.mentawaisurftravel.com/?cat=4
